Cathodic protection is stated as a technique that is used when there is a need to protect the surface of the metal from corrosion. This is done by making the metal surface a cathode of an electrochemical cell. The anode is made up of a sacrificial metal that can be easily corroded. In this way, the sacrificial metal corrodes and the protected metal remains safe.
For those structures which have greater length, an external source of direct current is provided to them. The steel is protected from rust by a coating of zinc. Cathodic protection tends to prevent stress corrosion cracking too.
